DUST-GUARD.

SPEClFICATION forming part of LettersPatent No. 677,611, dated July 2,1901.

Application filed February 25, 1901. Serial No. 481817. (No model.)

T0 all whom it may concern:

Be it known that I, JULIAN E. AKERS, a resident of Columbus, in thecounty of Franklin and State of Ohio, have invented certain new anduseful Improvements in Dust-Guards; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement i dust-guards for car-axle boxes,the object of the invention being to provide an improved device of thischaracter which will be extremely simple in construction, cheap tomanufacture, and which will when in use prevent any dust or grit fromentering the box.

With this object in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a view in elevation,illustrating my improvements. Fig. 2 is a view in section, and Fig. 3 isa top View.

1 represents the lower member of my improved guard, and 2 the uppermember. The lower member 1 is provided with a curved upper edge to fitagainst the lower half of the car-axle and with parallel uprights 3,having tongues 4 on their inner edges, to fit into grooves in the sideedges of the upper member 2 to prevent displacement of the latter, butpermit of its free vertical movement. The lower edge of the upper member2 is curved in the arc of a circle to engage the upper half of thecar-axle and, together with the lower member 1, entirely surrounds thesame to prevent any possibility of the entrance of dust or grit into thebox. The upper edge of the upper member 2 is grooved to receive a spring5, coiled between its ends, and the coil is located in the grooved upperedge of the member 2, and the respective ends of the spring 5 arelocated below pins 6 in the bifurcated upper ends of uprights 3 and bentupward at their extreme ends to prevent the escape of the spring endsfrom the pins 6. It will thus be seen that the ends of spring 5 ormetal, and instead of bifurcating the upper ends of uprights 3 toreceive the ends of the spring 5 I might bore a hole in each upright forthis purpose and secure the central portion of the spring to the uppermember 2 in any desired manner.

Various other slight changes might be resorted to in the general formand arrange ment of the several parts described without departing fromthe spirit and scope of my in vention, and hence I would have itunderstood that I do not wish to limit myself to the precise details setforth, but consider myself at liberty to make such slight changes andalterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- In a dust-guard, the combination of twomembers, both movable relatively to each other, the lower member havingtwo uprights and an intermediate curved face, the upper member having acurved lower face and mounted to slide in the uprights of the lowermember, one of said members having lateral tongues to move in verticalgrooves in the other member, the upper ends of the uprights and theupper end of the upper member having alined grooves, and a spring housedin said grooves, said spring being coiled between its ends and bearingupon the upper member to force it downwardly on a journal and the endsof the spring connected with said up rights and exerting an upward forceon said lower member to press it upwardly against the journal.

In testimony whereof I have signed this specification in the presence oftwo subscrib ing witnesses.

JULIAN E. AKERS.
